GHK-Cu50
Laboratory-grade research compound, prepared and packaged under controlled conditions. Not for human or animal consumption. For in vitro research use only.
Research Material Overview
GHK-Cu is the copper(II) complex of glycyl-L-histidyl-L-lysine (GHK), a naturally occurring tripeptide first isolated from human plasma. The copper-bound form has been investigated in connective tissue, wound healing, and antioxidant research models. CloudComps supplies GHK-Cu as a lyophilized research material for in vitro and laboratory investigation only.
Physical Description
Supplied as a blue lyophilized powder, reflecting the characteristic coloration of the copper(II) coordination complex, in a sealed glass vial. The material is hygroscopic; protect from moisture. Reconstitute with an appropriate sterile, research-grade solvent prior to in vitro use.

Purity & Testing Information
Reported purity of ≥ 99% is determined by RP-HPLC under the analytical conditions specified on the lot-specific Certificate of Analysis. Because GHK-Cu is a metal-peptide complex, accompanying documentation may also address copper content. Purity should be interpreted alongside the complete analytical documentation rather than as a standalone figure.
Available Documentation
- Lot-specific Certificate of Analysis (COA)
- RP-HPLC chromatogram with purity calculation
- Mass spectrometry (LC-MS) data
- Copper content assay
- Solubility and handling guidance
Storage Information
Store lyophilized material at -20°C in the original sealed vial, protected from light and moisture. After reconstitution, store at 2-8°C for short-term use. Avoid repeated freeze-thaw cycles. As a copper complex, the material should be handled in accordance with appropriate laboratory practices.
Frequently Asked Questions
Why is GHK-Cu blue?
The blue coloration is characteristic of the copper(II) coordination complex formed between the tripeptide glycyl-L-histidyl-L-lysine and copper ions. The color reflects the d-d electronic transitions of the bound copper center.
How does copper content factor into analysis?
Because GHK-Cu is a metal-peptide complex, analytical documentation may include copper content in addition to peptide purity. Researchers should review the complete COA to evaluate both the peptide and the metal complex.
Is GHK-Cu intended for human use?
No. The material supplied by CloudComps is for in vitro laboratory and scientific research only and is not for human or veterinary consumption.
